Application filed September 28. 1913. Serial No. 792,370.

To all whom it may concern:

Be it known that I, CHARLES THOMAS Moore, of Lancaster, in the county ofFairfield and State of Ohio, have invented certain new and usefulImprovements in De vices for. Capping OE Glass Cylinders; and I dohereby declare the following to be a and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

- My invention relates to tin-improvement in devices for capping-offglass cylinders, the objects being to provide improved means for holdingthe heating wire in contact with the cylinder, and for taking up theslack due to lengthening of the wire .while heated.

A further object is to provide a construction wherein the entirecircumference of the cylinder is exposed to contact with the wire.

\Vith these and other objects in View my invention consists in the partsand combination as will be more fully explained and pointed out in theclaims.

In the accompanying drawings, Figure 1 is a view in side elevationshowing my improvement applied to a glass cylinder; Fig. 2 is a view insection through the handle; Fig. 3 is a view of a modification, and Fig.l a' view in section through the handle.

1 represents a frame, semi-circular in shape and provided adjacent itstwo ends, and approximntely midway its ends, with the inwardlyprojecting fingers 2, 3 and 4. The fingers 2 t are each provided withcontact rollers riot-terminals 5, adapted to make contact with thecutting or cappingofi" wire 6, wnilc' thc finger 3 is forproperlyspacing the {frame l-from the glass cylinder 7. The finger 3 is providedwith an. elongated slot 8 lior the passage of'the thumb screw 9 whichlatter adjustably locks the finger to thelframe, and the finger 2carrying a contact' roller Sis pre} erably slidingly mounted in "ramc 1and acked up by. a spring as sho y'vn.

The frameiis made of nonconducting material and ie fingers ofl,conducting ma-' terial. The nine is of size'to conform o a stand" sizecylinder. The cylinders they or awn, are approximately of the be takencare of by making the fingers J 4 contact with the cylinder just abovethe greatestv diameter of cylinders of the standard size, and by makingtwo or more of the;

'minal 5,

be capped or cut, and when pro 1 the cylinder. placcd,.thc switch 15 beclosed, the current e diameter, and while they may vary heir lengths,such variations in size may r vary git different points throug a c a n dfingers adjustable as shown.

9 is a handle preferably formed integral with the frame 1, and is of asize to be conveniently grasped by one hand of the op erator, and 10 isa block mounted to slide in a. slot in the handle and provided at oneedge with rack teeth adapted o be engaged by the pawl 11, pivotallymounted on the handle. This block is preferably provided with tenonswhich rest and move in mortises 12 in the handle, 3 as to permit ofthemecessary movement of the sliding'block 10,.

and is connected by pins at its lower end to two ends of the cutting orcapping-off wire 7 which latter pass downwardly and cross "under theterminal5, in contact with each other and with-the terminal 5 so as toform the cylinder cutting loop. The finger 4 carrying the terminal 5,may be provided;

with loops or guides 4* for holding the wirev position with relation tothe terand the block 10 is provided with; a linger hole by which it maybe manipu-i in proper lated to let out or take up thewire wherebythesize of the cutting or capping-off loop thereof will be increased ordecreased.

13 and 14, are the current conducting wires, the latter of which leadsto the switch 15 on frame 1, and from thence to the terminal 5 i 2 onfinger 2 and is connected to the same, while the other wire 13, isconnected with terminal on finger 4.

In the operation of the device ptl'ie wire loop 7 is passed over the endof a cylinder to erly positioned thereon, is drawn taut -.a rear wardpull on block 1. is moved, it necessary, to carry the ter minal onfinger 2 into contact with the cutting-oil wire 6, at a. pointapproximately opposite the other terminal 5 so that the two terminals 5,engage thceutting 01f wire 6, approximatel on the longest diameter of Ifwhen the parts are so from the leading-in wire 14 will pass to theterminal 5 on finger 2, and as the latter is 1.0, after which'the framein electrical contact with he heating wire l 5 at the r side of thecylinder, the current and passing around i o beta directions, heat thesame i.

to crack the cylinder in the well known man-' ner,'and pass out throughthe terminal 5 on finger 4, and through the conductor 13 which isconnected with said terminal. Wh'en the parts are applied to a cylinder,the frame 1 is held properly spaced from the cylinder by the spacingfinger 3, and the heating wire loop 6 is closed onto the cylinder by thesliding block 10, and is held taut by the pawl 11. As the heating wireis continuous around the cylinder with its ends in contact, the entirecircumference of the cylinder will be heated, thus avoiding thenecessity ofshifting the device in order to complete the'heating. f

'In the construction shown in Figs. 3 and 4, I have made the" frame 1,intwo partseach of which is in the form ofa half circle with a handle 9at one end. Each part 2 0f the frame is provided adjacent its ends withterminal contacts and 5 and the latter of which are preferably sprinsupported as inFig. 1, so as to provide or cylinders of different sizes,and each alsocarries a section 0; the cutting off wire 6, each of whichis secured at one end to its respective terminal contact '5", and at itsother endto pins on cross arm carried by, the movable block 10 mountedin a slot in one handle section, each wire in its passage from contact 5to its cross arm, passing around or through and in'contact with itsterminal contact 5*. The block 10 is shown provided on one edge withratchet teethfwhichzare a'daptedto be engaged by the pawll-lfor lockingthe block against'movement in' a direction to loosennpf the cutting :01?wire and is also provided with a finger'hole for drawing the blockoutwardly. The current conducting wire 14 leads to the switch 15 in onesection and from'thence to tenn'inal contact 5 on the same section ofthe frame,- and the other wire 13 isconnecte'd withQtjhe;v terminalcontact 5 of the othersection of the frame. The twosections of the frameare locked together by the clamp 16 carried by one section and adaptedto engage locking means 17 on the other section. In applying the deviceto a glass cylinder, the sections of the frame are disconnectecl' andseparated so as to permit them to be prop-; erly placed on a cylinder,and when so placed, the terminals 5' will be-in contact with each other,andthe twoterminalsflfi."

will be in contact .with each other, so'that' a current-from conductor14, will pass froinf both terminals 5 through the two-wires-fif'f I tothe terminals 5 and from thence'tofcom' ductor 13. Ipr'efe'r tosuspendboth sec- 60 tions of the frame 1" fromatrolley 19 as shown inFig. 3, so that it can be-readily moved from one position to another-andremain suspended when not in use. While I have shown the endsof thecuttingoil wire" 5 secured to an adjustable block, it isevident its 'twends, it

,oss

that when a continuous wire is used,

Fig. 1, it may be secured at. oneend tofth' lrandle and the slack takenup by wrappi the other end around thefinger, as is now done with some ofthe capping-01f devices" .in use. Again in the construction shown 1n:Fig. 3 the terminals 5 and 5 on one see; tion make contact with thecorresponding terminals on the other-section, so that when";

the frame is applied to the cylinders, the two terminals 5 constituteone terminal, both for the conductor wire and also the heating wire loopand this is also true of the two terminals 5'. i

It is evident that many slight changes it the exact construction andarrangement of parts shown and described but,

Having fully described my invention what I claim as new and-desire tosecure by Letters-Patent, is z- -1. A capping'oif device for glasscylinders consistin of a frame shaped to conform .to the cylinder andhaving oppositely disposed terminals adapted to rest opposite each otheron opposite sides of the cylinder, heating means-contacting with bothofsaid terminals, means for taking up the slack. in said heating means, aconductor for-each of said terminals and a switch conductors.
